Click the sprites to make Jamal and Jordyn dance. Click each sprite to make a sound. Click the boom box to play a beat to match. Press space to stop the boom box playing. Better yet, try this with the Scratch Lab face sensing blocks to make them dance when you tilt your head! Download this project. Then, go to https://lab.scratch.mit.edu/face and click to try face sensing. Next, upload this project file and make the changes as indicated in the comments on the sprites when you see inside.
Thanks to @codifiedkid1, who is featured on the Scratch Lab Face Sensing page! She helped me create this.
